New research suggests that two episodes of erosion created the Dover Strait, as opposed to a single glacial lake spillover, as previously thought. New evidence supports the existing\u00a0theory of the initial erosion around 450,000 years ago, but also points out that a second erosion event was necessary to open the Strait. Authors suggest the definitive separation took place around 160,000 years ago, based on marine molluscs found in coastal sediment.<\/p>\n<p><strong>Authors:<\/strong><\/p>\n<p>Sanjeev Gupta, Jenny S.
